NOS3

A gene on chromosome 7q36 that encodes endothelial nitric oxide synthase (eNOS), a small molecule implicated in vascular smooth muscle relaxation through a cGMP-mediated signal transduction pathway. eNOS is a critical mediator of cardiovascular homeostasis that regulates the diameter of blood vessels and keeps vascular proliferation and apoptosis in check. It is upregulated by dynamin, porin and soluble guanylyl cyclase, and downregulated by interactions with Hsp90 and Cav-1 in the Golgi and by NOSIP and NOSTRIN at the plasma membrane. NOS3 is also a less preferred gene symbol for what is now designated as NANOS3, see there.
